welcome back to "hardball." we've gotten to the point in this campaign where you count hours, not days, and in this remaining precious time, you can tell where barack obama and mitt romney think this race will be won or lost. just take a look at their travel schedules through election day. for the president, colorado, iowa, wisconsin, ohio, new hampshire, virginia, and florida, of course. for governor romney, those same seven states plus his newly contested edition. he's going to pennsylvania. but zero in on today, and you can see what matters most, ohio, ohio, ohio as the late tim russert would say. three stops for the president and two for mitt romney who began his morning in wisconsin, another key rust belt battleground. congressman sherrod brown knows a little about buckeye state politics, and joan walsh is managing editor of salon.com and a political analyst. senator brown, sir, you know that state.
